A Painter leans his 12 foot ladder against the side of a house so that the base of the ladder is 6 feet from the house. How far up the side of the house does the ladder reach?

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

something over 10 so ? /10
